Construction at the intersection of Crewe Road and Route 17 is likely to affect traffic and may cause delays for motorists over the next three weeks.

A turn lane is being added, the traffic signal is being modified and adjustments will be made to the median at the intersection, said Charles Records, developer of the Coleman's Crossing mixed-use project. The improvements are related to the development that is located on Crewe Road just past the Boys & Girls Club.

There will be a detour in place and periodic lane closures most days from 8 a.m. to 5 p.m., Records said. The big ditch between McDonald's and Crewe Road will be where most of the work takes place, he said.

Once the improvements are complete, there will be two lanes of exit from Crewe Road onto Route 17 and the big ditch will no longer exist, Records said.
